I have an American Standard Vent Away one piece toilet installed in a pool cabanna room at my home. I will be turning the water to those rooms on, as soon as there is no more frost here in Pa. Are ther still parts available for the vent away toilet, should I have a problem? How does that vent work anyway? Or maybe I should have my plumber install an up to date fixture. Any thoughts from a plumber? Thanks in advance for any help. tommy
